Highlights of Solar and Geomagnetic Activity 28 September - 04 October 2020

Solar activity was very low throughout the period. No active regions with sunspots were observed and no Earth-directed CMEs were detected. 

No proton events were observed at geosynchronous orbit.

The greater than 2 MeV electron flux at geosynchronous orbit reached high levels on 28 Sep-04 Oct. 

Geomagnetic field activity reached active to G1 (Minor) geomagnetic storm levels on 28 Sep, with quiet to active levels observed on 29  Sep-01 Oct, due to positive polarity CH HSS influences. Quiet and quiet to unsettled conditions were observed throughout the remainder of the period under a nominal solar wind regime. 

Forecast of Solar and Geomagnetic Activity 05 October - 31 October 2020

Solar activity is expected to be very low throughout the outlook period. 

No proton events are expected at geosynchronous orbit.

The greater than 2 MeV electron flux at geosynchronous orbit is expected to reach high levels on 05-10 Oct, and 21-31 Oct. Normal to moderate levels are expected on 11-20 Oct. 

Geomagnetic field activity is likely to reach G2 (Moderate) geomagnetic storm levels on 25 Oct, with G1 (Minor) geomagnetic  storms likely on 21-24 Oct, due to the anticipated influences of recurrent, positive polarity CH HSSs. Active conditions are expected on 20, 26-28 Oct. Quiet and quiet to the unsettled conditions are expected to prevail throughout the remainder of the outlook period.
